Renting or buying an apartment in Sydney’s Eastern Suburbs can be exciting. The area offers convenient access to beaches, public transport, shopping precincts and established residential neighbourhoods. However, before signing a lease or committing to a property purchase, it is important to look beyond the apartment’s appearance.
Fresh paint, renovated kitchens and modern flooring can sometimes conceal pest-related problems. Apartments may still be affected by cockroaches, rodents, termites, ants and other pests, even when the individual unit appears clean and well-maintained.
A careful inspection can help you identify potential warning signs before they become an expensive or stressful problem. Here are seven pest indicators to check when inspecting an apartment in the Eastern Suburbs.
1. Cockroach Droppings in Kitchens and Bathrooms
Cockroaches are one of the most common pests found in apartment buildings. They are attracted to warmth, moisture, food scraps and hidden spaces around plumbing and appliances.
During an inspection, look inside kitchen cupboards, under sinks and around the dishwasher, refrigerator and oven. Cockroach droppings may appear as small black specks, dark smears or pepper-like marks.
Bathrooms and laundries should also be checked carefully, particularly around drains, pipe openings and vanity cabinets.
A small number of droppings may indicate that cockroaches are entering from another apartment, shared service cavity or rubbish area. Because apartment units are connected through plumbing, wall voids and common spaces, pest activity may not be limited to one residence.
2. Unusual Smells in Cupboards or Enclosed Areas
Persistent odours can sometimes indicate hidden pest activity.
Cockroach infestations may produce a musty or oily smell, particularly when large numbers are present. Rodent activity can create a stale, ammonia-like odour caused by urine and nesting materials.
Open cupboards, wardrobes, storage spaces and under-sink cabinets during the property inspection. Pay attention to smells that remain even when the apartment appears clean.
Unusual odours should not automatically be assumed to come from old plumbing or poor ventilation. They may indicate pest activity behind walls, under flooring or inside cabinetry.
3. Gnaw Marks, Scratching Sounds or Rodent Droppings
Rats and mice can enter apartment buildings through roof spaces, basements, garages, rubbish rooms and utility openings. Once inside, they may travel between units using wall cavities and service ducts.
Look for gnaw marks on timber, plastic containers, cables, cupboard edges and stored items. Rodent droppings are usually dark, narrow and shaped like small grains of rice.
You may also hear scratching, movement or tapping sounds inside walls or ceilings, particularly during quieter periods.
Rodents can damage wiring, contaminate food preparation areas and create unpleasant odours. Their presence may also indicate access gaps elsewhere in the building that require attention.
4. Moisture Damage Around Walls, Windows and Plumbing
Moisture does not always mean a property has a pest problem, but it can create conditions that attract pests.
Check for water stains, peeling paint, swollen skirting boards, mould, damp cupboards and leaking taps. Pay particular attention to bathrooms, laundries, balconies and areas beneath kitchen sinks.
Cockroaches, silverfish and ants are often drawn to damp environments. Moist timber can also increase the risk of termite activity, particularly in ground-floor apartments, older buildings and properties with timber features.
Visible water damage should be investigated because ongoing moisture can support pest activity and cause structural deterioration.
5. Hollow-Sounding or Damaged Timber
Termites are generally associated with houses, but apartments are not automatically protected from them. Ground-floor units, older apartment blocks, buildings with landscaped areas and complexes containing timber structures may still be vulnerable.
Inspect timber door frames, skirting boards, flooring and built-in cupboards for blistering, cracking or unusual softness. Timber that sounds hollow when lightly tapped may require further assessment.
Other possible termite indicators include mud-like material around cracks, damaged timber edges and discarded wings near windows.
A professional building and pest inspection should be considered before buying an apartment, particularly if there is suspicious timber damage. When active termites are confirmed, professional Termite Treatment may be needed to manage the infestation and reduce the risk of further damage. Treatment should always be based on a proper inspection and identification of the affected areas.
6. Ant Trails Near Windows, Balconies or Kitchen Areas
A few ants may not seem concerning, but repeated ant trails can indicate a nest nearby.
Check window frames, balcony doors, kitchen benches, pantry areas and gaps around plumbing. Ants may enter apartments through very small cracks or travel between units through wall cavities.
Sugary spills, grease, pet food and moisture often attract them. Simply wiping away the visible trail may provide only temporary relief because the colony can remain hidden elsewhere.
Ongoing ant activity may suggest that the apartment has unsealed entry points or that the wider building has an established pest issue.
7. Pest Traps, Sprays or Freshly Sealed Gaps
Visible pest-control products can provide useful clues during an inspection.
Look for cockroach baits, rodent traps, insect sprays, moth traps or pest powder inside cupboards and storage areas. Fresh sealant around pipes, skirting boards and cabinet gaps may also indicate that someone has recently attempted to block pest entry points.
These measures do not necessarily mean the property currently has a serious infestation. However, they are reasonable signs that pest activity may have occurred previously.
Ask the property manager, owner or selling agent whether the apartment has had pest treatments and whether the building maintains a regular pest management program.

Check the Common Areas as Well
Pest problems in apartment buildings often begin outside the individual unit.
Inspect rubbish rooms, shared laundries, underground parking areas, gardens, storage cages and hallways where possible. Overflowing bins, food waste, damaged drainage and poorly maintained gardens can attract rodents, cockroaches and ants.
The condition of common areas can provide a useful indication of how well the building is managed. Even a clean apartment may experience recurring pest problems when the surrounding areas are not properly maintained.
Questions to Ask Before Signing
Before renting or buying, ask whether there have been recent pest complaints within the building. You can also ask whether pest management is handled by the owners corporation, strata manager, landlord or individual occupants.
Buyers should review strata records where available. These records may contain information about past termite inspections, pest treatments, water leaks or building maintenance issues.
Tenants may also wish to clarify who is responsible for pest treatment if a problem develops after moving in.
Final Thoughts
An apartment inspection should involve more than checking the layout, natural light and storage space. Pest warning signs can be subtle, and overlooking them may lead to ongoing inconvenience, treatment costs or property damage.
Check kitchens, bathrooms, timber features, storage spaces and common areas carefully. Look for droppings, moisture, damage, unusual smells and signs of previous pest-control activity.
When buying, a qualified building and pest inspection can provide additional confidence before settlement. When renting, raising concerns before signing the lease can help clarify the property’s condition and the responsibilities of everyone involved.
Taking a few extra minutes to check for pest warning signs may help you make a more informed decision and avoid unpleasant surprises after moving in.
